I have been trying to figure out how this works. I know what the answer is since someone else has previously posted the answer in the forums. I want to learn how to do it though. Here is the question: A 3.0 kg bucket is being lowered by a rope into a 10 m deep well, starting from the top. The tension in the rope is 9.8 N. The acceleration of the bucket will be: 6.5 m/s/s downward. He used the following formula Net F / m = a which is 19.66 / 3.0 kg = 6.5 m/s/s. How did he get the 19.66??
